Bio Chapter 8

  1. autotroph
    organism that can capture energy from sunlight or chemicals & use it to produce its own food from inorganic compounds
  2. heterotroph
    organism that obtains energy from the food it consumes
  3. adenosine triphosphate (ATP)
    one of the principal chemical compounds that living things use to store & release energy
  4. photosynthesis
    process by which plants & some other organisms use light energy to convert water & carbon dioxide into oxygen & high-energy carbohydrates such as sugars & starches
  5. pigment
    light-absorbing molecule
  6. chlorophyll
    principal pigment of plants & other photosynthetic organisms; captures light energy
  7. thylakoid (disc)
    saclike photosynthetic membrane found in chloroplasts
  8. photosystem
    light-collecting units of chloroplast
  9. stroma
    region outside the thylakoid membranes in chloroplasts
  10. light-dependent reaction
    reactions of photosynthesis that use energy from light to produce ATP & NADPH
  11. Calvin cycle
    reactions of photosynthesis in which energy from ATP & NADPH is used to build high-energy compounds such as sugars
